9.<br> Find the slope of the line.<br><br><br><br> A. -1/4<br><br> B. 4<br><br> C. 1/4<br><br> D. -4
slamgirl [31]

Answer:

9. A. -1/4

Step-by-step explanation:

Plug the points into the equation y2-y1/x2-x1. In this case, I chose the points (0,-2) and (4,-3). This would make the equation -3--2/4-0. This would be equal to -3+2/4 or -1/4. Therefore, the slope is -1/4.

If this has helped you please mark as brainliest
